I don't know what to do about this, please help

I have never made an actual post like this on Pettalk, but this feels urgent. I’m 16 years old, and my girlfriend, who just turned 16, has a dog named Waffles that she loves more than anyone in the world. Waffles and her bond are one of the only things keeping her happy. Unfortunately, she lives with a terrible, non-biological dad who treats her extremely unfairly. He constantly says mean things and treats her poorly compared to how he treats his biological daughter. My girlfriend is really tired of it and has decided to move in with her mother. In the past, her non-bio dad said she could keep Waffles when she moves out, but suddenly today he said he might find a better home for the dog because he doesn’t like her. This is the same dog that brings my girlfriend so much joy in a tough situation. I genuinely need advice on how to persuade him to let her keep Waffles. I’m starting to really hate him for even considering this. What can I tell her?

Have your girlfriend talk to him directly about how much Waffles means to her. Emphasize the bond they share and how important that is for her well-being.

It might help to explain that getting rid of Waffles would just make everything worse for her. He should understand that if he truly cares about her happiness, he wouldn’t want to take away her support.

If he’s open to it, maybe suggest a compromise. Can she take Waffles with her to her mom’s place? That way, he won’t have to worry about finding another home for the dog.

If he’s still resistant, perhaps she could involve her mom in the conversation. Having another adult there might help him see things from a different perspective.

It might also help to gather some evidence of Waffles being well cared for and loved. If she can show that she’s responsible, it may sway him.
